AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
347 AM PDT Wed Aug 20 2014

.Synopsis...
Near to slightly cooler than normal temperatures expected through
the weekend. A slight chance of thunderstorms will be possible
over the Sierra Nevada to the south of Lake Tahoe late today.

&&

.Discussion...
Closed upper low is over the Channel Islands off the coast of
SoCal early this morning. Skies are mostly clear across the region
except for marine stratus which is once again working its way
inland from the Bay Area into the southern Sacramento Valley as
moderately strong onshore flow continues and the marine layer
remains deep. Temperatures are running within a few degrees of
readings 24 hours ago except across the north valley where
temperatures are milder this morning.

A slim chance of thunderstorms will be possible late today across
the Sierra Nevada to the south of Lake Tahoe, otherwise dry
weather is expected through at least the weekend. Relatively
cool temperatures will continue the next few days, though we`ll
start to lose a bit of delta breeze influence later today, and
more so the next few days. This will allow for a bit more warming
across interior Northern California heading into the weekend.

&&

.Aviation...
Mainly VFR conditions the next 24 hours across interior Northern
California. Areas of marine stratus moving into the Delta with
patchy stratus inland into the southern Sacramento valley through
about 16z for possible MVFR/IFR ceilings across Sacramento TAF
sites. Isolated Thunderstorms possible Sierra crest south of Tahoe
this afternoon and evening. South to west winds 10-15 kt except
near the delta southwest winds 15-25 knots.

&&

.STO Watches/Warnings/Advisories...None.
